		<h2><a name="CompleteChangeLog-OSCache2.4"></a>OSCache 2.4</h2>
		<h3><a name="CompleteChangeLog-ReleaseNotes"></a>Release Notes</h3>

		<p>(1st Mai 2007 - by Lars Torunski)</p>

		<h4><a name="CompleteChangeLog-Newfeaturesandenhancements"></a>New
		features and enhancements</h4>

		<p>Furthermore the next major release 2.4 enhances the CacheFilter
		and allows a better integration with the <a
			href="http://www.springframework.org/"
			title="Visit page outside Confluence">Spring Framework</a> and <a
			href="JMX Monitoring.html" title="JMX Monitoring">JMX Monitoring</a>.</p>

		<ul>
			<li>Setting CacheFilter parameters runtime</li>
			<li>Lazy initialization in CacheFilter in order to ease spring
			integration</li>
			<li>Allow disabling cacheing for special http methods (e.g.
			POST/DELETE/PUT) in CacheFilter</li>
			<li>CacheFilter allow reentrance over different filter
			configurations</li>
		</ul>


		<ul>
			<li>Hibernate 3.2 integration support</li>
			<li>JMX Monitoring/Administration via Spring</li>
			<li>Improve oscache.properties loading</li>
			<li>Performance improvment for large disk persistence usage</li>
		</ul>


		<h4><a name="CompleteChangeLog-UpgradeGuide"></a>Upgrade Guide</h4>

		<ul>
			<li>Due to the enhancements in the CacheFilter and method
			signature changes, it's recommended to recompile your code.</li>
			<li>Due to changes for CACHE-284 the handling of the listeners
			have been changed: Before OSCache 2.4 objects which implemented
			different CacheEventListener (e.g. CacheEntryEventListener and
			CacheMapAccessEventListener) had to be added twice, because the
			listeners where registrated only for one special event listener. With
			OSCache 2.4 only the object has to be added to the list without the
			2nd parameter 'type of the listener'.</li>
		</ul>

		Notes - Release Candidate</h3>

		<p>(18th September 2005 - by Lars Torunski)</p>

		<h4><a
			name="CompleteChangeLog-Besidesbugsbeingfixed%2CmajorimprovementshavebeenmadetotheCacheFilterinmanyways%3A"></a>Besides
		bugs being fixed, major improvements have been made to the CacheFilter
		in many ways:</h4>

		<ul>
			<li>Default initialization of the last modified header which
			reduces transaction overhead and server load</li>
			<li>Support of GZip filters in the filter chain</li>
			<li>Custom key generation by subclassing CacheFilter or by
			implementing a special interface</li>
			<li>Preserving more http headers, e.g. the expires header</li>
			<li>Special handling for fragments of a page</li>
			<li>Avoids session creation for application scope pages</li>
			<li>Multiple matching cache filters won't dead-lock the response
			anymore</li>
		</ul>

		<h3><a name="CompleteChangeLog-ReleaseNotes"></a>Release Notes</h3>

		<p>(1st May 2005 - by Andres March)</p>

		<h4><a name="CompleteChangeLog-Improvements%3A"></a>Improvements:</h4>

		<ul>
			<li>The taglib URI was changed to <tt><a
				href="http://www.opensymphony.com/oscache"
				title="Visit page outside Confluence">http://www.opensymphony.com/oscache</a></tt>
			in <a href="http://jira.opensymphony.com/browse/CACHE-61"
				title="Visit page outside Confluence">CACHE-61</a></li>
			<li>The DiskPersistenceListener escapes '?' now and guarantees
			that the filenames will be unique based on the cache key, see <a
				href="http://jira.opensymphony.com/browse/CACHE-110"
				title="Visit page outside Confluence">CACHE-110</a></li>
			<li>Session objects in cache tags are created only if necessary,
			see <a href="http://jira.opensymphony.com/browse/CACHE-88"
				title="Visit page outside Confluence">CACHE-88</a></li>
			<li>The disk persistence configuration key can be accessed now,
			see <a href="http://jira.opensymphony.com/browse/CACHE-111"
				title="Visit page outside Confluence">CACHE-111</a></li>
		</ul>



		<h4><a name="CompleteChangeLog-BugFixes%3A"></a>Bug Fixes:</h4>

		<ul>
			<li>The CacheFilter doesn't send back a 304 (not modified)
			response when client cache is de-activated anymore, see <a
				href="http://jira.opensymphony.com/browse/CACHE-116"
				title="Visit page outside Confluence">CACHE-116</a></li>
			<li>CacheFilter doesn't support correctly i18N by setting
			encoding not properly, <a
				href="http://jira.opensymphony.com/browse/CACHE-38"
				title="Visit page outside Confluence">CACHE-38</a> and <a
				href="http://jira.opensymphony.com/browse/CACHE-159"
				title="Visit page outside Confluence">CACHE-159</a></li>
			<li>Cron expressions - leap days not always matched correctly, <a
				href="http://jira.opensymphony.com/browse/CACHE-157"
				title="Visit page outside Confluence">CACHE-157</a></li>
			<li>FindBugs doesn't report that the usage of GetResource may be
			unsafe if class Config is extended anymore, see <a
				href="http://jira.opensymphony.com/browse/CACHE-108"
				title="Visit page outside Confluence">CACHE-108</a></li>
			<li>ConcurrentModificationException on flushGroup, see <a
				href="http://jira.opensymphony.com/browse/CACHE-127"
				title="Visit page outside Confluence">CACHE-127</a></li>
			<li>Exception not thrown when not serializable object is
			persisted instead stack trace is persisted, see <a
				href="http://jira.opensymphony.com/browse/CACHE-112"
				title="Visit page outside Confluence">CACHE-112</a></li>
			<li>A few concurrency issues were fixed, see <a
				href="http://jira.opensymphony.com/browse/CACHE-170"
				title="Visit page outside Confluence">CACHE-170</a>, <a
				href="http://jira.opensymphony.com/browse/CACHE-167"

				title="Visit page outside Confluence">CACHE-127</a></li>
		</ul>


		<h4><a
			name="CompleteChangeLog-Changesthatmayaffectbackwardscompatibility%3A"></a>Changes
		that may affect backwards compatibility:</h4>

		<ul>
			<li>The improvement <a
				href="http://jira.opensymphony.com/browse/CACHE-88"
				title="Visit page outside Confluence">CACHE-88</a> may change the
			behaviour of the application, because a session object isn't created
			anymore even if it wasn't necessary. A web application may react
			different to a not existing session object.</li>
			<li>The URI change of <a
				href="http://jira.opensymphony.com/browse/CACHE-61"
				title="Visit page outside Confluence">CACHE-61</a> from <tt>/oscache</tt>
			to <tt><a href="http://www.opensymphony.com/oscache"
				title="Visit page outside Confluence">http://www.opensymphony.com/oscache</a></tt>
			affects all JSP's which explicit use the old URI.</li>

			persisted when the memory capacity has been exceeded. The property is
			called: cache.persistence.overflow.only. It defaults to false for
			backwards compatibility meaning all cache entries are persisted when
			a listener has been registered. See <a

			expression will be considered stale. This is exposed to the cache tag
			via the 'cron' attribute. See cronTest.jsp for examples.</li>
			<li>Event listener support has been refactored and improved. It
			is now possible to specify a comma-delimited list of event listeners
			using this property. Previously only one class could be specified.
			Events listed here should implement the CacheEntryEventListener
			and/or the ScopeEventListener interfaces.</li>
			<li>New event CacheMapAccessEvent.STALE_HIT. This event is fired
			when an attempt is made to retrieve and entry from the cache, and the
			entry is found but is stale.</li>
			<li>Clustering support has been added as an event listener.
			Currently it is implemented using <a href="http://www.javagroups.com"
				title="Visit page outside Confluence">JavaGroups </a>. To enable,
			just add the BroadcastingCacheEventListener class to the
			cache.event.listeners property.</li>
			<li>Now uses Jakarta Commons Logging for all log messages. This
			means that the cache.debug configuration property is now ignored -
			use whatever logging configuration is appropriate for your logging
			setup instead. -Fabian Crabus</li>
			<li><a href="http://jira.opensymphony.com/browse/CACHE-14"
				title="Visit page outside Confluence">CACHE-14, Matthias Nott </a>
			Now allows for content to be cached indefinitely without expiration.</li>
			<li>The build.xml &lt;javac ...&gt; directives now specify
			debug="true".</li>
			<li>Performance boost: When OSCache is running on JRE 1.4 or
			higher, LRUCache and FIFOCache use a LinkedHashSet instead of a
			LinkedList.</li>
			<li>Japloy is now used to ensure source is consistently
			formatted.</li>
			<li>Test cases now work on non-windows platforms. Also coverage
			reports added courtesy of clover.</li>

		<h4><a
			name="CompleteChangeLog-Changesthatmayaffectbackwardscompatibility%3A"></a>Changes
		that may affect backwards compatibility:</h4>

		<ul>
			<li>The cache.entryevent.classes property in the configuration
			file has been renamed to cache.event.listeners, since it accepts
			CacheEntryEventListener, ScopeEventListener and
			CacheMapAccessEventListener types.</li>
			<li>The cache.persistence.classes property has been renamed to
			cache.persistence.class since it is only possible to specify one
			PersistenceListener.</li>
			<li>For consistency, cache.unlimited_disk is now
			cache.unlimited.disk and cache.useHostDomainInKey is now
			cache.use.host.domain.in.key.</li>
			<li>The oscache.tld file now uses a taglib 1.2 DTD.</li>
			<li>To build OSCache, JDK 1.4.x or higher is required. There is
			however no runtime dependency on JDK 1.4.x.</li>
			<li>The Cache.flushPattern() method and &lt;cache:flush
			pattern="..."/&gt; are deprecated. You are instead encouraged to
			group your cache entries when you add them to the cache and then use
			the Cache.flushGroup() method or the &lt;cache:flush group="..."/&gt;
			tag to flush an entire cache group.</li>
			<li>Disk persistence now puts all files in the same directory.
			This has a number of side effects. Keys &gt;255 chars will cause
			problems. Also, similar keys might get mapped to the same file. For
			example, it is very inadvisable to have two keys with the names
			'my_key' and 'my.key'.</li>
			<li>GeneralCacheAdministrator is no longer static. Users that
			relied on this behaviour can still hold onto a static reference to it
			with minor code changes.</li>
			<li>When a NeedsRefreshException is thrown, it is now vital that
			the cache entry is either updated, or Cache.cancelUpdate(key) is
			called to release the lock on this cache entry. This is a consequence
			of the fix for <a href="http://jira.opensymphony.com/browse/CACHE-42"
				title="Visit page outside Confluence">CACHE-42 </a>.</li>
			<li>CacheProperties class was removed. It didn't work on 1.7.5
			anyway. The same effect can be achieved by specifying a subclass of
			Properties.</li>
			<li>Autogenerated cache keys now contain the request method (eg,
			HEAD, GET, etc).</li>
			<li>OSCache has been repackaged from
			"com.opensymphony.module.oscache.&#42;" to
			"com.opensymphony.oscache.&#42;". Any code or configuration files
			that refer to "com.opensymphony.module.oscache" will need to be
			updated.</li>

		<ul>
			<li>Session caches (created using the ServletCacheAdministrator)

			heavy load to get its persistent session caches confused across
			sessions.<br />
			o Session caches will not work in a clustered environment.<br />
			o Session caches have the same settings global settings applied to

		fbeauregard@pyxis-tech.com, and<br />
		Alain Bergevin, abergevin@pyxis-tech.com, of Pyxis Technologies Inc.)</p>

		<p>This version include some refactoring, corrections and new
		features.<br />
		Here are the highlights:</p>

		<ul>
			<li>CacheAdministrator has been split in 3. We have now
			AbstractCacheAdministrator, and ServletCacheAdministrator and
			GeneralCacheAdministrator extends it</li>
			<li>Packages have been adjusted. We now have oscache.base,
			oscache.general and oscache.Servlet.<br />
			Adjustement must be made to the oscache.tld</li>
			<li>ServletCacheHashMap has been created in order to reflect
			specific needs for Servlets. It extends CacheHashMap</li>
			<li>Support for multiple cache tag in a single page, without
			supplying a key. Nested cache tag are not yet supported (you need to
			manage keys in that case).</li>
			<li>OSCache can now cache any objects (not only JSP content)
			using GeneralCacheAdministrator</li>
			<li>GenerateKey now support suffixes (used to deal with multiple
			cache tags)</li>
			<li>A complete JUnit test suite has been created for osCache,
			including a JSP and a Servlet</li>
			<li>Added the required libraries for the test unit. The JUnit
			JAR has been upgraded to version 3.7</li>
			<li>Required libraries are now HHTPUnit, Tidy, JUnit 3.7 and
			JUnitPerf</li>
			<li>The cBuffer variable used for keyGeneration has been moved
			locally to GenerateKey since it was a threading issue</li>
			<li>The build file has been modified to include test running</li>
			<li>The flushAll method is now abstract since
			CacheAbstractAdministrator can't know all valid scopes</li>
			<li>Removed the retry logic for disk cache read and write (not
			used anymore)</li>
			<li>Fixed an issue with the needsRefresh method which returned
			an invalid value when invoked first by returning true and then
			invoked having to return false. Both case returned true.</li>
			<li>The doStartTag method in CacheTag has been modified to
			prevent returning null when cache content is missing (cache file
			deleted)</li>
			<li>The doAfterBody method in CacheTag has been modified in
			order to prevent hitting the cache twice in some situation</li>
			<li>The useBody method in CacheTag has been renamed to
			setUseBody in order to reflect its usage</li>
			<li>LoadProperties interface added to CacheProperties</li>
			<li>Added a NeedsRefreshException</li>
			<li>Retrofited the changed made by Kesav Kumar in order to
			retrieve the sessionId correctly</li>
			<li>Added code toughness to avoid working with invalid
			parameters in public methods</li>
			<li>Magic numbers and strings are now declared as constants</li>
			<li>Many methods are now declared as final or protected</li>
			<li>Imports are now more accurate, no more *</li>
			<li>Comments and some headers modified to reflect JavaDoc
			standard</li>
		</ul>


		<h2><a name="CompleteChangeLog-OSCache1.6.1"></a>OSCache 1.6.1</h2>
		<h3><a name="CompleteChangeLog-ReleaseNotes"></a>Release Notes</h3>

		<p>(16th September, 2001 - by Todd Gochenour,
		tgochenour@peregrine.com)</p>

		<ul>
			<li>Removed attribute "encoding" in all areas, since Object
			serialization stores strings in UTF-8 format, encoding is no longer
			necessary.</li>
			<li>Added Synchronization to getCacheEntry() to insure multiple
			threads do not access HashMap and get erroneous results.</li>
			<li>Implemented property cache.useHostDomainInKey (true/false)
			to prepend URL request server name to cache key when cache used by
			multiple servers. The "cache.domainname" property found in
			oscache.properties (not used in code) was removed.</li>
			<li>Corrected file caching logic so that multiple processes can
			share cache information (file locking). Missing still is the ability
			to signal processes that a cache needs to be flushed when using
			Memory Caching along with File Caching.</li>
			<li>Unit testing revealed some minor configuration bugs which
			were corrected.</li>
		</ul>



		<h2><a name="CompleteChangeLog-OSCache1.6"></a>OSCache 1.6</h2>
		<h3><a name="CompleteChangeLog-ReleaseNotes"></a>Release Notes</h3>

		<p>(5th September, 2001 - by Mike Cannon-Brookes,
		mike@atlassian.com)</p>

		<ul>
			<li>Changed the CacheEntry so that it caches Object rather than
			String (allowing image caching) (Serge Knystautas,
			sergek@lokitech.com)</li>
			<li>Cached objects are now serialized to disk so cannot be read
			by humans anymore (this allows us to cache Object) (Serge Knystautas,
			sergek@lokitech.com)</li>
			<li>Added a Servlet 2.3 CacheFilter (and associated response
			classes) that caches whole requests (Serge Knystautas,
			sergek@lokitech.com)</li>
			<li>Minor changes to CacheAdministrator (the way Cache and
			CacheEntry's are retrieved) - merging Serge and Todd's changes</li>
		</ul>



		<h2><a name="CompleteChangeLog-OSCache1.5"></a>OSCache 1.5</h2>
		<h3><a name="CompleteChangeLog-ReleaseNotes"></a>Release Notes</h3>

		<p>(6th August, 2001 - by Todd Gochenour,
		tgochenour@peregrine.com)</p>

		<ul>
			<li>Added boolean "cache.memory" attribute to oscache.properties
			to eliminate memory consumption and rely strictly on disk storage.</li>
			<li>Added three interfaces "CacheLog", "CacheProperties", and
			"CacheContents" to allow plugable implementations for these
			functions. The CacheContents interface allows the pages to be cached
			using a database.</li>
			<li>Added "Language" attribute to CacheTag and FlushTag to
			distinguish a page that supports I18N generation. The ISO-639
			language code is used when the scope of the page is "Application".
			The code defines a subdirectory under the "application" directory of
			file caching.</li>
			<li>Modified the CacheAdministrator.generateKey() function to
			append the request's QueryString to the URI when automatically
			generating keys. The QueryString is encoded using the MD5 digest
			base64 algorithms.</li>
			<li>Added attribute "encoding" to a CacheTag so that the file IO
			does proper conversion when reading and writing the cache files. (per
			suggestion of Pedro Gomez)</li>
			<li>Added retries when SecurityException is thrown. Java has no
			built in exclusive file locking implementations. The file is written
			to a lock file and then renamed as an atomic operation so that
			multiple processes on the same box can reliable access cache data.</li>
			<li>Added "pattern" attribute to FlushTag which invokes a
			CacheHashMap.flushPattern() function to scan for and flush all keys
			that contain the value of the pattern. (per suggestion of Todd
			Rudrick)</li>
			<li>Added support for a CacheTag time value of zero which turns
			off caching for that tag. (per suggestion of Pedro Gomez)</li>
		</ul>
